2mm Universal Flat Deadlock Intumescent – Complete Fire Door Safety Upgrade for ZUKFD Deadlocks
Introduction
The 2mm Universal Flat Deadlock Intumescent is a premium, high-performance fire safety accessory designed for ZUKFD flat deadlocks. This product is engineered to protect the most vulnerable area of fire-rated doors—the lock cavity—ensuring compliance with FD30 and FD60 fire ratings. Its slim 2 mm profile allows discreet installation behind logos, signage, or decorative panels, so your doors maintain their aesthetic integrity without compromising on safety.
Constructed from graphite-based intumescent material, this pad expands automatically under heat, sealing gaps around the deadlock to block flames, smoke, and hot gases. Its maintenance-free design ensures long-lasting, reliable protection for residential, commercial, and public buildings.
Power Statement: Installing the 2mm Universal Flat Deadlock Intumescent is not just an upgrade—it’s a life-saving investment for every door in your property.
How the 2mm Universal Flat Deadlock Intumescent Works
The 2mm Universal Flat Deadlock Intumescent uses advanced graphite technology that reacts precisely at 180°C. When heat is applied, the pad expands 5–10 times its original thickness, forming a dense barrier that prevents flames, smoke, and hot gases from spreading through the lock cavity.
Key benefits of this reaction:
- Rapid Response: The pad reacts immediately, ensuring fire containment.
- Gap Sealing: Blocks all gaps around the deadlock, even in uneven or deep mortices.
- Fire Door Integration: Works seamlessly with hinges, smoke seals, and door closers for a complete fire-resistant system.
- Discreet Installation: Completely hidden behind hardware, logos, or decorative elements.
